Description

The error popup is most likely caused by a WPanel (with several WPushButtons) hidden on creation and setHidden(false) later (after establishing a connection).
In addition, this panel suffers from WHBoxLayout::setSpacing() not having an effect until the page is reloaded in the browser.

Updated by Michael Seibt 23 days ago

Urgent : Still reproducible with Wt 4.12.2.

Caused by disabling a WPanel on creation and enabling it later.

STR:

--> Popup "Wt internal error; code: undefined, description: can't access property "resizeItem", Wt4_12_2.$(...).layout is undefined"
and dead session

(The error in the trace output in the bug description was unrelated. It has been resolved by doubling max-formdata-size to 40960.)

But with this small app, a JavaScript error is traced. (With the actual app, it takes ~ 90 seconds until the error floods the trace.)
